            <Canvas x:Name="zoomBar" Width="96.092" Height="20" Canvas.Top="1" Visibility="Collapsed">
                <Rectangle Width="100" Height="20" Fill="#FFFFFFFF" Stroke="#FF000000" />
                <Rectangle Width="98" Height="18" Canvas.Top="1" Canvas.Left="1" Fill="#FFDDDDDD" Clip="M0,18 L0,14 L98,1 L98,18"/>
                <Rectangle x:Name="zoomIndicator" Height="18" Canvas.Top="1" Canvas.Left="1" Fill="#FF000000" Clip="M0,18 L0,14 L98,1 L98,18"/>
            </Canvas>
            <Canvas x:Name="zoomOut" Cursor="Hand" Width="25" Height="20">
                <Image x:Name="ZoomOut" Height="Auto" Cursor="Hand"  Source="Images/zoom_out.png" Width="16" Canvas.Left="3.093" Canvas.Top="0.024"  Stretch="Uniform"/>
            </Canvas>
        </StackPanel>
    </Grid>
</UserControl>



И теперь не работают кнопки, stackpanel стала неактивна. Уже второй день мучаюсь, но ничего не получается.
Подскажите, пожалуйста, в чем причина?

Канва в канве, да еще все это в гриду.
Всего две строки в основном гриде и большая куча элементов только в первой.
Для начала убери все canvas. Rectangle замени на бордюры. Это упростит код. Добовляй не все сразу, а поэлементно пока нет четкого понимания

SeVa, спасибо.
Упростил конструкцию, убрал канвасы и все заработало.
